SOOOOO useful, no faults at all

Totally great!!!

Much needed add on

Can't live it without it. Thank you.

Macht was es soll. Ein weiteres TMP ersatz Bausteinchen in der addon liste.

This works quit nicely. Although using right-click context menu for the list is a bit confusing and it has unrelated items like "Remove from toolbar". Why don't use a dropdown menu?
Another suggestion is to add a "Clear closed tabs" to empty the list, and a "Restore all tabs".

I use it all the time and works as promised. I only wish I could give you more than 25 websites, which is a restriction that Firefox imposes due to their new add-on system.

Better than similar addons. Left click re-opens last tab and right click opens a menu to select closed tabs from.

Works as intended. Thanks, but what happens when the max number of closed tabs is reached...?

(Edit: OK, it starts replacing the oldest closed tabs).

Could you add an option to clear the closed tabs list...? Thx.

好用，在FF57下工作一切正常。

Perfect. It does what is says.

Simple, good enough, nice icon fitting the new Quantum UI. One suggestion though: Add information about modifying "browser.sessionstore.max_tabs_undo" in about:config. By default, it is set to 10, took me a while to figure out why I can only see 5 closed tabs in the submenu, when in add-on settings I had 25....
